Round three of the Charity Challenge, a "grudge race" between "Papa John" Schnatter and Don Schumacher Racing’s Leah Pritchett, who drives the Papa John's Pizza Top Fuel dragster, is scheduled for the Fallen Patriots Route 66 NHRA Nationals presented by K&N, and "Papa John" has been working hard preparing for the bout.

Round three of the Charity Challenge, a "grudge race" between "Papa John" Schnatter and Don Schumacher Racing’s Top Fuel Leah Pritchett, who drives the Papa John's Pizza Top Fuel dragster, is scheduled for the Fallen Patriots Route 66 NHRA Nationals presented by K&N.

Pritchett has beaten her benefactor two straight times this season – in Charlotte and Gainesville – and has raised $40,000 this year to help Infinite Hero, but Papa John is coming to Chicago better prepared after testing in Indy with the assistance of his “secret weapon” Top Fuel champ Antron Brown.

Pritchett has used a supercharged Gen III HEMI in a 2017 Dodge Challenger configured for drag racing to beat Schnatter's prized 1971 Camaro Z28, the same car he bought for $1,600 when he was 15 years old from money he made washing dishes at Rocky's Sub Pub in his hometown of Jeffersonville, Ind., and later sold to help his father's tavern survive bankruptcy.
